Description
editPlants in the genus Streptoglossa are shrubs, or annual or perennial herbs, often aromatic, with simple, often glandular leaves. The daisy-like flowers are pink to purple and have 15 to 100 or more fertile florets, the outer florets female with a lobed ligule, and the disc florets bisexual and tube-shaped. There are 3 to 6 rows of overlapping involucral bracts at the base of the heads. The fruit is a hairy achene, the pappus with many barbed or feathery bristles.[2][3][4]
Taxonomy
editThe genus Streptoglossa was first formally described by Joachim Steetz, but published in 1863 by Ferdinand von Mueller in the Edinburgh New Philosophical Journal.[5] Mueller used the opportunity of publishing the name, to refer to Steetz as "my lamented friend the late Dr Joachim Steetz of Hamburg, in whom botanical science has lost one of its most able, correct, and philosophical promoters of this age."[6] The genus name means "twisted tongue", probably referring to the bracts that twist when dry.[7]
